ABSTRACT
Los quistes óseos aneurismáticos del área de cabeza y cuello representan menos del 5% de todos los tumores óseos. Son lesiones benignas, que comúnmente afectan las metáfisis de los huesos largos y las vértebras como en el caso que se describe a continuación, simulando una lesión de la rinofaringe. Se describe su manejo y tratamiento.
The aneurismal of bone cyst of the head and neck localization, represent less than the 5% of the all bone tumors. They are benign lesions, and commonly affecting the metaphysis of the long bones and vertebrae, like in the case we described below, it simulating the rhino pharynx lesion. We describe the management and treatment.

The case describes a young girl developing cervicofacial emphysema after fall. She presented in emergency with gradually worsening upper body swelling without any sign of distress. Swelling was found on the right side of the face, all around the neck and right arm with crepitus in all these areas. CT scanning of head, neck and chest were performed and a small area of communication between nasopharynx and the trapped air of subcutaneous emphysema was seen. Video-endoscopy of the pharynx showed a tear in the nasopharyngeal mucosa acting as a one way valve leading to the development of cervicofacial emphysema

El virus de Epstein-Barr se encuentra en relación directa con algunas neoplasias como los linfomas y el carcinoma indiferenciado de nasofaringe. Más recientemente se han reportado la presencia del genoma viral en tumores similares a linfoepiteliomas de otras localizaciones como estómago, hígado, mama y pulmón. Fueron tomadas muestras en fresco de pacientes con tumores localizados en tracto aerodigestivo superior entre enero y junio de 2006. Se determinó el genoma viral. Dieciocho de 41 muestras eran positivas para virus, 23 negativas. Trece de los tumores malignos resultaron positivos para el genoma del virus mientras que el 48,1 por ciento restante resultaron negativos. La presencia del genoma viral fue encontrada en 8 muestras de laringe, 4 de nasofaringe, 2 de senos piriformes y en 1 de cada una de los siguientes sitios: fosas nasales, mucosa yugal, amígdala, y antro maxilar. A pesar del número limitado de muestras tomadas en algunas de las localizaciones mencionadas en este trabajo, pudimos encontrar el genoma viral en sitios como laringe, fosas nasales y cavidad oral. La mayor parte de los tumores malignos eran carcinomas escamosos, sólo 2 muestras correspondían a linfoepiteliomas. El genoma del virus puede ser identificado en muestras tomadas en fresco de tumores del tracto aerodigestivo superior tales como en carcinomas escamosos de laringe, fosas nasales, cavidad oral y faringe. Es necesario realizar más estudios para poder identificar la posible relación que existe entre este virus y dichos tumores.
The Epstein-Barr virus is been related with many malignancies as lymphoma and nasopharyngeal undifferentiated carcinoma. More recently, the presence of viral genome had been reported in some similar tumors how the lymphoepithelioma in other localizations for example the stomach, the liver, the breast and lung. From January to June 2006, we had taken fresh from the patients superior aero digestive tumors samples. The Epstein-Barr viral genome was determined by the Polymerasa Chain Reaction. From 41 samples of tumors, 18 were viruses positive and 23 of them were viruses negative. Thirteen malignant tumors were positive for the viruses genome and the rest ant other 48.1 % were negative. In eight larynxes, 4 nasopharyngeal, 2 piriform sinuses and some of this localization: nasal cavity, oral yugal mucosa, tonsil and maxillary sinus, and samples the viral genome of Epstein Barr was present. Although, we had a limited number of sample in some regions mentioned in these work, we could determine the viral genome of Epstein Barr in some sites how larynx, nasal and oral cavity. The majority of malignant tumors were squamous cell carcinoma, only two of them were correspondent to lymphoepithelioma. The Epstein-Barr viral genome may be identified in fresh superior aero digestive tumors samples, like in squamous cell carcinoma of the larynx, the oral cavity, nasal cavity and in the pharynx. Further studies are necessary to identify the probability relation between this virus and these tumors.

Os autores descrevem um caso raro de obstrucao nasal provocado por sinequia de palato e rinofaringe, pos-infeccao oro-naso-sinusal grave e entubacao nasogastrica prolongada. O quadro clinico e semelhante ao da obstrucao nasal cronica causada pela hipertrofia de adenoide. O tratamento cirurgico foi realizado com sucesso
